- No. Links are generated entirely in your browser. Your phone number and message are never sent to any server.
- Does it work on mobile?
- Yes. sms: links open the native Messages app on iOS and Android.
- Why do iOS and Android use different sms: link formats?
- iOS uses "sms:+1234?&body=Hello" (ampersand before body) while Android uses "sms:+1234?body=Hello" (question mark). The tool detects your device and builds the correct format automatically.
